Apart from above aberrant measurements of LFUV ratios, there are other measurements which involve only observables related to decay modes induced by the quark level transition \(b \rightarrow s\, \mu ^+\,\mu ^-\) . These observables are mainly related to \(B \rightarrow K^* \, \mu ^+\,\mu ^-\)  and \(B_s \rightarrow \phi \, \mu ^+\,\mu ^-\)  decay modes. The measured value of the optimized angular observable \(P^{\prime }_5\)  in \(B \rightarrow K^* \, \mu ^+\,\mu ^-\)  in 4.0 \(\mathrm {GeV}^2 \le q^2 \le \)  6.0 \(\mathrm {GeV}^2\)  bin deviates from the SM prediction at the level of 3\(\sigma \)  [1]}, [2]}, [3]}, [4]}. Further, the experimental value of the branching ratio of \(B_s \rightarrow \phi \, \mu ^+\,\mu ^-\)  decay nonconcur with the SM prediction at the level of 3.5\(\sigma \)  level [5]}, [6]}. Moreover, there is dissimilitude in the measured and SM prediction of the branching ratio \(B_s \rightarrow \mu ^+ \mu ^-\)  decay [7]}, [8]}, [9]}, [10]}, [11]}, [12]}. These disparities can be accommodated by assuming LFUV new physics with imperative couplings to muons. One can also accommodate these aberrations by assuming universal couplings to leptons. However, such a scenario cannot conciliate anomalous measurements related to the LFUV ratios.
